Description

本発明は、焼却炉およびボイラを含む焼却プラントに関する。   The present invention relates to an incineration plant including an incinerator and a boiler.

従来から、ごみや汚泥などの廃棄物を焼却する焼却炉と、この焼却炉から排出される排ガスから熱を回収するためのボイラを含む焼却プラントが知られている。ボイラは、焼却炉からの排ガスが流れる排ガス経路を含み、この排ガス経路の壁面に多数の水管が設けられるとともに、水管の下流側では排ガス経路中に過熱器が配置される。   Conventionally, an incinerator that incinerates wastes such as garbage and sludge and an incineration plant that includes a boiler for recovering heat from exhaust gas discharged from the incinerator are known. The boiler includes an exhaust gas path through which exhaust gas from the incinerator flows. A number of water pipes are provided on the wall surface of the exhaust gas path, and a superheater is disposed in the exhaust gas path on the downstream side of the water pipe.

排ガス経路内の受熱面（例えば、水管や過熱器の表面）には排ガスに含まれるダストが付着するため、受熱面に付着したダストを定期的に除去する必要がある。受熱面に付着したダストを除去するための装置としては、従来では、受熱面に向けて蒸気を噴射する蒸気式スートブロワが用いられていた。近年では、蒸気式スートブロワに代えて、衝撃波式スートブロワを用いることが提案されている（例えば、特許文献１参照）。   Since dust contained in the exhaust gas adheres to the heat receiving surface (for example, the surface of a water pipe or a superheater) in the exhaust gas path, it is necessary to periodically remove the dust attached to the heat receiving surface. As a device for removing dust adhering to the heat receiving surface, conventionally, a steam soot blower that injects steam toward the heat receiving surface has been used. In recent years, it has been proposed to use a shock wave type soot blower instead of a steam type soot blower (see, for example, Patent Document 1).

衝撃波式スートブロワは、燃料ガスおよび酸素を含む混合気を燃焼させて衝撃波を発生させ、この衝撃波を排ガス経路中に放出するものである。この衝撃波の放出により、受熱面からダストが除去される。例えば、燃料ガスはメタンガスである。   The shock wave soot blower burns an air-fuel mixture containing fuel gas and oxygen to generate a shock wave, and releases the shock wave into an exhaust gas path. Dust is removed from the heat receiving surface by the release of the shock wave. For example, the fuel gas is methane gas.

特開２０１７−２０７７３号公報JP 2017-20773 A

ところで、衝撃波式スートブロワを用いた場合には、衝撃波式スートブロワへ燃料ガスを供給する必要がある。燃料ガスがメタンガスである場合、メタンガスを充填した複数のボンベを焼却プラント内に設置し、これらのボンベからメタンガスを衝撃波式スートブロワへ供給することが考えられる。   By the way, when a shock wave soot blower is used, it is necessary to supply fuel gas to the shock wave soot blower. When the fuel gas is methane gas, it is conceivable to install a plurality of cylinders filled with methane gas in the incineration plant and supply the methane gas from these cylinders to the shock wave soot blower.

しかしながら、メタンガスを充填したボンベを用いた場合には、ボンベ１本当たりの価格が高いばかりでなく、ボンベの交換作業が煩雑である。   However, when a cylinder filled with methane gas is used, not only is the price per cylinder high, but the replacement of the cylinder is complicated.

そこで、本発明は、ボンベを用いずに衝撃波式スートブロワへ燃料ガスを供給することができる焼却プラントを提供することを目的とする。   Therefore, an object of the present invention is to provide an incineration plant capable of supplying fuel gas to a shock wave type soot blower without using a cylinder.

前記課題を解決するために、本発明の焼却プラントは、廃棄物を焼却する焼却炉と、前記焼却炉からの排ガスが流れる排ガス経路を含むボイラと、燃料ガスおよび酸素を含む混合気を燃焼させて衝撃波を発生させ、この衝撃波を前記排ガス経路中に放出する衝撃波式スートブロワと、前記廃棄物を発酵させてバイオガスを生成する発酵槽と、前記発酵槽から前記衝撃波式スートブロワへ前記バイオガスを前記燃料ガスとして供給する供給ラインと、を備える、ことを特徴とする。   In order to solve the above-mentioned problems, an incineration plant of the present invention burns an incinerator for incinerating waste, a boiler including an exhaust gas path through which exhaust gas from the incinerator flows, and a mixture containing fuel gas and oxygen. A shock wave sootblower that generates a shock wave and releases the shock wave into the exhaust gas path, a fermenter that ferments the waste to produce biogas, and the biogas from the fermenter to the shock wave soot blower. And a supply line that supplies the fuel gas.

上記の構成によれば、焼却炉に併設される発酵槽で生成されるバイオガスを衝撃波式スートブロワの燃料ガスとして利用することができる。このため、ボンベを用いずに衝撃波式スートブロワへ燃料ガスを供給することができる。   According to said structure, the biogas produced | generated with the fermenter attached to an incinerator can be utilized as a fuel gas of a shock wave type soot blower. For this reason, fuel gas can be supplied to a shock wave type soot blower without using a cylinder.

上記の焼却プラントは、前記供給ラインに設けられた、前記バイオガスを貯留するタンクと、前記タンクの上流側または下流側で前記供給ラインに設けられた、前記バイオガスからメタン以外の少なくとも１つの成分を除去して前記バイオガスを精製する精製装置と、をさらに備えてもよい。この構成によれば、メタン濃度の高いバイオガスを衝撃波式スートブロワへ供給することができる。特に、精製装置がタンクの上流側に設けられていれば、タンクに貯留されたメタン濃度の高いバイオガスを、電力会社などへ売却することもできる。   The incineration plant includes a tank for storing the biogas provided in the supply line, and at least one of the biogas other than methane provided in the supply line on the upstream side or the downstream side of the tank. And a purification device that purifies the biogas by removing components. According to this configuration, biogas having a high methane concentration can be supplied to the shock wave soot blower. In particular, if the purification apparatus is provided on the upstream side of the tank, the biogas having a high methane concentration stored in the tank can be sold to an electric power company or the like.

本発明によれば、ボンベを用いずに衝撃波式スートブロワへ燃料ガスを供給することができる。   According to the present invention, fuel gas can be supplied to a shock wave soot blower without using a cylinder.

図１に、本発明の一実施形態に係る焼却プラント１を示す。この焼却プラント１は、ごみや汚泥などの廃棄物を焼却する焼却炉２と、焼却炉２から排出される排ガスから熱を回収するためのボイラ３を含む。   FIG. 1 shows an incineration plant 1 according to an embodiment of the present invention. The incineration plant 1 includes an incinerator 2 that incinerates waste such as garbage and sludge, and a boiler 3 for recovering heat from exhaust gas discharged from the incinerator 2.

本実施形態では、焼却炉２がストーカ式であり、乾燥ストーカ２４、燃焼ストーカ２５および後燃焼ストーカ２６を含む。ただし、焼却炉２は、流動床式であってもよい。   In the present embodiment, the incinerator 2 is a stoker type, and includes a dry stoker 24, a combustion stoker 25, and a post-combustion stoker 26. However, the incinerator 2 may be a fluidized bed type.

具体的に、焼却炉２は、ホッパー２１、給じん機２２、主燃焼室２３および再燃焼室２７を含む。上述したストーカ２４〜２６は主燃焼室２３の底面を構成している。ホッパー２１には、図略のクレーンにより廃棄物が投入される。給じん機２２は、所定のインターバルで間欠的に作動することにより、ホッパー２１内の廃棄物を主燃焼室２３内に送り込む。   Specifically, the incinerator 2 includes a hopper 21, a dust feeder 22, a main combustion chamber 23, and a recombustion chamber 27. The above-described stokers 24 to 26 constitute the bottom surface of the main combustion chamber 23. Waste is put into the hopper 21 by a crane (not shown). The dust feeder 22 is intermittently operated at a predetermined interval, thereby sending the waste in the hopper 21 into the main combustion chamber 23.

本実施形態では、主燃焼室２３が、廃棄物の移動方向と同方向に燃焼ガスが流れる並行流型である。再燃焼室２７は、主燃焼室２３から流出する燃焼ガスの向きを反転させる。より詳しくは、再燃焼室２７は、燃焼ガスの流れ方向において主燃焼室２３の下流側端部から主燃焼室２３と重なるように斜め上向きに延びている。ただし、主燃焼室２３は必ずしも並行流型である必要はなく、主燃焼室２３内で燃焼ガスが上向きに流れるように、再燃焼室２７が主燃焼室２３の中央から上向きに延びてもよい。   In the present embodiment, the main combustion chamber 23 is a parallel flow type in which the combustion gas flows in the same direction as the movement direction of the waste. The recombustion chamber 27 reverses the direction of the combustion gas flowing out from the main combustion chamber 23. More specifically, the recombustion chamber 27 extends obliquely upward so as to overlap the main combustion chamber 23 from the downstream end of the main combustion chamber 23 in the flow direction of the combustion gas. However, the main combustion chamber 23 is not necessarily a parallel flow type, and the recombustion chamber 27 may extend upward from the center of the main combustion chamber 23 so that the combustion gas flows upward in the main combustion chamber 23. .

ボイラ３は、焼却炉２からの排ガスが流れる排ガス経路３１を含む。排ガス経路３１は、再燃焼室２７の上方に配置された放射室（第１煙道）３２と、放射室３２と上部同士が連通する第２煙道３３と、第２煙道３３と下部同士が連通する第３煙道３４を含む。放射室３２および第２煙道３３の壁面には多数の水管が設けられており、これらの水管内で発生した水蒸気がボイラドラム３５に収集される。ボイラドラム３５に収集された水蒸気は、第３煙道３４中に配置された過熱器３６，３７に送られて過熱され、その後に発電機５２と連結されたタービン５１に送られて発電に利用される。   The boiler 3 includes an exhaust gas path 31 through which exhaust gas from the incinerator 2 flows. The exhaust gas path 31 includes a radiation chamber (first flue) 32 disposed above the recombustion chamber 27, a second flue 33 in which the upper portion communicates with the radiation chamber 32, and a second flue 33 and the lower portion. Includes a third flue 34 in communication. A large number of water pipes are provided on the wall surfaces of the radiation chamber 32 and the second flue 33, and water vapor generated in these water pipes is collected in the boiler drum 35. The steam collected in the boiler drum 35 is sent to superheaters 36 and 37 disposed in the third flue 34 and superheated, and then sent to a turbine 51 connected to a generator 52 for use in power generation. Is done.

ボイラ３には、少なくとも１つの衝撃波式スートブロワ（以下、ＳＰＳと略す）４が設けられている。ＳＰＳ４は、燃料ガスおよび酸素を含む混合気を燃焼させて衝撃波を発生させ、この衝撃波を排ガス経路３１中に放出するものである。ＳＰＳ４は、所定のインターバルで間欠的に作動する。   The boiler 3 is provided with at least one shock wave soot blower (hereinafter abbreviated as SPS) 4. The SPS 4 burns an air-fuel mixture containing fuel gas and oxygen to generate a shock wave, and releases the shock wave into the exhaust gas path 31. The SPS 4 operates intermittently at a predetermined interval.

本実施形態では、２つのＳＰＳ４が第２煙道３３および第３煙道３４にそれぞれ設けられている。第３煙道３４に設けられたＳＰＳ４は、２つの過熱器３６，３７の間に位置している。ただし、ＳＰＳ４の数および位置は、適宜変更可能である。   In the present embodiment, two SPSs 4 are provided in the second flue 33 and the third flue 34, respectively. The SPS 4 provided in the third flue 34 is located between the two superheaters 36 and 37. However, the number and position of the SPS 4 can be changed as appropriate.

より詳しくは、各ＳＰＳ４は、図２に示すように、図略のピストンを内蔵する本体４１およびシリンダ４２と、本体４１からシリンダ４２と反対向きに延び、先端が排ガス経路の壁面を貫通するノズル４３と、本体４１からノズル４３と直交するように延びる一対の燃焼室４４を含む。ピストンは、燃焼室４４の内部をノズル４３の内部から遮断したりノズル４３の内部と連通させたりする。   More specifically, as shown in FIG. 2, each SPS 4 includes a main body 41 and a cylinder 42 containing a piston (not shown), a nozzle extending from the main body 41 in the direction opposite to the cylinder 42, and a tip penetrating the wall of the exhaust gas path 43 and a pair of combustion chambers 44 extending from the main body 41 so as to be orthogonal to the nozzle 43. The piston blocks the inside of the combustion chamber 44 from the inside of the nozzle 43 or communicates with the inside of the nozzle 43.

さらに、本体４１には、バルブユニット４７が取り付けられており、このバルブユニット４７に燃料ガス貯留室４５および酸素貯留室４６が接続されている。バルブユニット４７は、燃料ガス貯留室４５および酸素貯留室４６の内部を、一対の燃焼室４４の内部から遮断したり一対の燃焼室４４の内部と連通させたりする。燃料ガス貯留室４５および酸素貯留室４６の内部が一対の燃焼室４４の内部と連通すると、燃料ガス貯留室４５から燃焼室４４へ燃料ガスが供給されるとともに酸素貯留室４６から燃焼室４４へ酸素が供給され、それらが燃焼室４４内で混合される。その後、混合気に点火されて混合気が燃焼されるとともに図略のピストンが燃焼室４４の内部をノズル４３の内部と連通させ、これにより衝撃波が発生する。   Further, a valve unit 47 is attached to the main body 41, and a fuel gas storage chamber 45 and an oxygen storage chamber 46 are connected to the valve unit 47. The valve unit 47 blocks the inside of the fuel gas storage chamber 45 and the oxygen storage chamber 46 from the inside of the pair of combustion chambers 44 or allows the inside of the pair of combustion chambers 44 to communicate with each other. When the inside of the fuel gas storage chamber 45 and the oxygen storage chamber 46 communicates with the inside of the pair of combustion chambers 44, fuel gas is supplied from the fuel gas storage chamber 45 to the combustion chamber 44 and also from the oxygen storage chamber 46 to the combustion chamber 44. Oxygen is supplied and they are mixed in the combustion chamber 44. Thereafter, the air-fuel mixture is ignited and the air-fuel mixture is combusted, and a piston (not shown) communicates the inside of the combustion chamber 44 with the inside of the nozzle 43, thereby generating a shock wave.

酸素貯留室４６は、酸素供給ライン７により複数の酸素ボンベ７１と接続されている。なお、図２では、代表として１つのＳＰＳ４のみを描いている。酸素供給ライン７には、各酸素ボンベ７１の近傍に、酸素ボンベ７１の交換時に使用される開閉弁７２が設けられている。ただし、酸素貯留室４６に代えて空気貯留室が採用され、この空気貯留室に圧縮機から空気が供給されてもよい。図示は省略するが、酸素供給ライン７には酸素ボンベ７１から流出した酸素の圧力を所定圧力まで低下させる減圧弁が設けられている。   The oxygen storage chamber 46 is connected to a plurality of oxygen cylinders 71 by the oxygen supply line 7. In FIG. 2, only one SPS 4 is drawn as a representative. In the oxygen supply line 7, an open / close valve 72 used when the oxygen cylinder 71 is replaced is provided in the vicinity of each oxygen cylinder 71. However, an air storage chamber may be employed instead of the oxygen storage chamber 46, and air may be supplied from the compressor to the air storage chamber. Although not shown, the oxygen supply line 7 is provided with a pressure reducing valve that reduces the pressure of oxygen flowing out from the oxygen cylinder 71 to a predetermined pressure.

燃料ガス貯留室４５は、図１および図２に示すように、燃料ガス供給ライン６により複数の発酵槽６１と接続されている。なお、図１では燃料ガス供給ライン６の上流側部分のみを図示し、燃料ガス供給ライン６の下流側部分は図２に示す。   As shown in FIGS. 1 and 2, the fuel gas storage chamber 45 is connected to a plurality of fermenters 61 by a fuel gas supply line 6. In FIG. 1, only the upstream portion of the fuel gas supply line 6 is shown, and the downstream portion of the fuel gas supply line 6 is shown in FIG.

各発酵槽６１は、廃棄物を発酵させてバイオガスを生成する。つまり、燃料ガス供給ライン６は、発酵槽６１からＳＰＳ４へバイオガスを燃料ガスとして供給する。   Each fermenter 61 ferments waste to produce biogas. That is, the fuel gas supply line 6 supplies biogas from the fermenter 61 to the SPS 4 as fuel gas.

図１および図２に示すように、燃料ガス供給ライン６には、上流側から順に、タンク６２、精製装置６３および圧縮機６４が設けられている。タンク６２は、バイオガスを貯留する。精製装置６３は、バイオガスからメタン以外の少なくとも１つの成分を除去してバイオガスを精製する。ただし、精製装置６３は、タンク６２の上流側に配置されてもよい。圧縮機６４は、燃料ガスであるバイオガスの圧力を酸素と同程度の圧力まで上昇させる。   As shown in FIGS. 1 and 2, the fuel gas supply line 6 is provided with a tank 62, a purification device 63, and a compressor 64 in order from the upstream side. The tank 62 stores biogas. The purifier 63 purifies the biogas by removing at least one component other than methane from the biogas. However, the purification device 63 may be disposed on the upstream side of the tank 62. The compressor 64 raises the pressure of the biogas that is the fuel gas to a pressure comparable to that of oxygen.

バイオガスは、主成分として、メタン、二酸化炭素および水蒸気を含み、微量成分として、硫化水素、アンモニアおよびシロキサンなどを含む。精製装置６３により除去される成分は、微量成分の１つまたはいくつかであることが望ましい。また、精製装置６３は、微量成分に加えて二酸化炭素および水蒸気をバイオガスから除去してもよい。   Biogas includes methane, carbon dioxide, and water vapor as main components, and includes hydrogen sulfide, ammonia, siloxane, and the like as trace components. The component removed by the purifier 63 is desirably one or several of the trace components. Moreover, the refiner | purifier 63 may remove a carbon dioxide and water vapor | steam from biogas in addition to a trace component.

以上説明したように、本実施形態の焼却プラント１では、焼却炉２に併設される発酵槽６１で生成されるバイオガスをＳＰＳ４の燃料ガスとして利用することができる。このため、ボンベを用いずにＳＰＳ４へ燃料ガスを供給することができる。   As described above, in the incineration plant 1 of the present embodiment, the biogas generated in the fermenter 61 provided in the incinerator 2 can be used as the fuel gas for the SPS 4. For this reason, fuel gas can be supplied to SPS4, without using a cylinder.

なお、廃棄物がごみである場合には、発酵槽６１ではごみ中の有機物が有効に利用される一方で、発酵槽６１において大量の残渣が発生する。しかしながら、発酵槽６１が焼却炉２に併設されていれば、その残渣を廃棄物として焼却炉２で焼却することができる。換言すれば、本実施形態の構成によれば、ＳＰＳ４用の燃料ガスをごみから製造する場合の、大量に発生する残渣を何らかの方法で処理しなければならないというデメリットを克服することができる。   When the waste is waste, the fermenter 61 effectively uses organic matter in the waste, while a large amount of residue is generated in the fermenter 61. However, if the fermenter 61 is attached to the incinerator 2, the residue can be incinerated in the incinerator 2 as waste. In other words, according to the configuration of the present embodiment, it is possible to overcome the demerit that a large amount of residue must be processed by some method when the fuel gas for SPS 4 is produced from garbage.

しかも、本実施形態では、燃料ガス供給ライン６に精製装置６３が設けられているので、メタン濃度の高いバイオガスをＳＰＳ４へ供給することができる。特に、本実施形態とは逆に精製装置６３がタンク６２の上流側に設けられていれば、タンク６２に貯留されたメタン濃度の高いバイオガスを、電力会社などへ売却することもできる。   In addition, in the present embodiment, since the purification device 63 is provided in the fuel gas supply line 6, it is possible to supply biogas having a high methane concentration to the SPS4. In particular, in contrast to the present embodiment, if the refining device 63 is provided on the upstream side of the tank 62, the biogas having a high methane concentration stored in the tank 62 can be sold to an electric power company or the like.

なお、本発明は上述した実施形態に限定されるものではなく、本発明の要旨を逸脱しない範囲で種々の変形が可能である。   In addition, this invention is not limited to embodiment mentioned above, A various deformation | transformation is possible in the range which does not deviate from the summary of this invention.

例えば、燃料ガス供給ライン６には精製装置６３が設けられていなくてもよい。ただし、この場合には、バイオガス中に含まれる硫化水素やシロキサンなどが配管や弁などを腐食させることがある。これに対し、燃料ガス供給ライン６に精製装置６３が設けられていれば、そのような配管や弁などの腐食を抑制することができる。   For example, the refiner 63 may not be provided in the fuel gas supply line 6. In this case, however, hydrogen sulfide, siloxane, etc. contained in the biogas may corrode the piping and valves. On the other hand, if the refining device 63 is provided in the fuel gas supply line 6, corrosion of such pipes and valves can be suppressed.
